Fourier representations of velocity, pressure and magnetic field have been used to transform the original partial differential equations into systems of ordinary differential equations (ODE), to which then special numerical methods for the qualitative analysis of systems of ODE have been applied, supplemented by the simulative calculation of solutions for selected initial conditions. In a part of the calculations, in order to reduce the number of modes to be retained, the concept of approximate inertial manifolds has been applied. For varying (increasing from zero) strength of the imposed forcing, or varying Reynolds number, respectively, time-asymptotic states, notably stable stationary solutions, have been traced. A primary non- magnetic steady state loses, in a Hopf bifurcation, stability to a periodic state with a non-vanishing magnetic field, showing the appearance of a generic dynamo effect. From now on the magnetic field is present for all values of the forcing. The Hopf bifurcation is followed by further, symmetry-breaking, bifurcations, leading finally to chaos. We pay particular attention to kinetic and magnetic helicities. The dynamo effect is observed only if the forcing is chosen such that a mean kinetic helicity is generated; otherwise the magnetic field diffuses away, and the time-asymptotic states are non-magnetic, in accordance with traditional kinematic dynamo theory.}, language = {en} } @book{DuitMikelskis1996, author = {Duit, Reinders and Mikelskis, Helmut}, title = {Physik, um die Welt zu begreifen : ein Lehrbuch f{\"u}r die Jahrgangsstufe 9/10 ; [Hauptbd.], Nordrhein- Westfalen}, publisher = {Diesterweg [u.a.]}, address = {Frankfurt am Main [u.a.]}, isbn = {3-425-03673-4}, pages = {184 S.}, year = {1996}, language = {de} } @article{HoepfnerFruebingNeumannetal.1996, author = {H{\"o}pfner, Ulf and Fr{\"u}bing, Peter and Neumann, Werner and Kaminorz, Yvette and Brehmer, Ludwig}, title = {Polarization Processes of poly(DMDAAC) films studied by TSD current}, year = {1996}, language = {en} } @phdthesis{Bruegmann1996, author = {Br{\"u}gmann, Bernd}, title = {Quantum gravity in four dimensions : canonical quantization and dynamical triangulations}, pages = {17 S.}, year = {1996}, language = {en} } @phdthesis{Braun1996, author = {Braun, Michael}, title = {Sternentstehung in irregul{\"a}ren Galaxien : UGCA 86 und die Magellanschen Wolken}, pages = {88 S. : Ill.}, year = {1996}, language = {de} } @article{KrampeSchwarzWitt1996, author = {Krampe, Ralf-Thomas and Schwarz, Udo and Witt, Annette}, title = {Measures of complexity in signal analysis}, year = {1996}, language = {en} } @article{OsipovRosenblumPikovskijetal.1997, author = {Osipov, Grigory V. and Rosenblum, Michael and Pikovskij, Arkadij and Zaks, Michael A. and Kurths, J{\"u}rgen}, title = {Attractor-repeller collision and eyelet intermittency at the transition to phase synchronization}, year = {1997}, abstract = {The chaotically driven circle map is considered as the simplest model ofphase synchronization of a chaotic continuous-time oscillator by external periodic force.

These changes have been analysed by a combination of X-ray specular reflectivity data, X-ray grazing incidence diffraction data and scanning force microscopy images, On the basis of these experimental data we have simulated possible supramolecular structures, These simulations provide insight into the intermolecular interactions giving rise to the observed structural transitions. The crystalline structure induced by thermal treatment of the LB films is characterized by a uniaxial texture, which is correlated with the dipping direction during deposition of the LB film.}, language = {en} }
